[5] Financed by private funds and the German-Ethiopian Foundation, Uhlig established the Hiob Ludolf Visiting Professorship in 2003/04, which deals with topics from politics, business and society.
It scientific encyclopaedia provides with 4365 articles on Ethiopia and the neighbouring regions; it covers topics from history, languages, literature, ethnology, religion, culture, society and art.
